Short summary
We report on the high-temperature piezoresistivity of carbon-containing silicon oxycarbide nanocomposites (C/SiOC). The piezoresistive behavior of the C/SiOC nanocomposites relies on the presence of dispersed nanocrystalline graphite and non-crystalline carbon domains. In comparison to highly ordered carbon, C/SiOC exhibits strongly enhanced sensitivities, even at high temperatures. Thus, k values of ca. 80 at the highest temperature reading, 1200°C, reveal that C/SiOC is a primary candidate.
